5 A bit of History

6 JBoss 3.x/ 4.x JMX Microkernel cons 6 > NO native support for POJOs > NO configuration API Hard to persist configuration changes Hard to provide advance tool support > Ad- hoc ex tensibility Implicit/ hidden dependencies Few clean internal APIs/ SPIs > Ability to Embed and/ or Unit test JMX dependency No standalone project

7 JBoss 5 Goals (1) 7 > Java EE 5 Certification > Take every major subsystem to the next level Clustering infrastructure Messaging service Security modules Transaction manager Web services stack Web server

8 JBoss 5 Goals (2) 8 > Build a Nex tgen server runtime architecture POJO based kernel (JBoss Microcontainer) Small, Standalone, Embedable, Testable > New Aspectized Deployer Framework > New Configuration API (Profile Service) > New Classloading Architecture > Multi- component model support POJOs Legacy JMX MBean services OSGi bundles whatever comes next

11 JBoss 5 Architecture

12 The Big Picture JBoss AS 5 Runtime service.x ml spring beans 12 > Runtime components wired together by the Microcontainer with dependencies [and aspects] applied across component models > Support any existing (and future) component model that makes sense POJO.ear MBean.war Java EE Aspectized User Applications OSGi Component Deployers Spring Virtual Deployer Framework jboss- beans Messaging Clustering Security Transactions JBoss MicroContainer OSGi bundle Enterprise Services OR Mapping WS Web Server JVM

13 JBoss Microcontainer (MC) 13 > A complete IoC framework > A kernel for managing services > With tight JBoss AOP integration > Virtual Deployment Framework > Fully extensible Managed Classloading Deployers VFS Reflection Kernel OSGi MDR JMX Reliance

14 Not Invented Here (NIH) Syndrome? 14 > Why not just use an existing OSGi runtime? Remember the JMX- based Microkernel? Avoid repeating the same mistakes! > Full control of the runtime A superset of what ex isting technologies offer Allow deep integration with the deployment machinery > A future- proof base Do not change core with the next technology swift Make components of different type, first class citizens

15 JBoss Microcontainer Kernel 15 > The JBoss MC Kernel is essentially a state machine > It transforms a complete metadata description into runtime objects > Moving them through a set of states to control their lifecycle and configuration Deploy Undeploy

16 Virtual Deployment Framework 16 > Processing pipeline that transforms input to output metadata > Ordered by Phases and Inputs/ Outputs > Manipulating the deployment metadata (attachments) > Integrate at any given point in the chain! > A VFS abstracts the actual deployments NOT_INSTALLED PARSE PRE_DESCRIBE CLASSLOADER PRE_REAL POST_PARSE DESCRIBED REAL POST_CLASSLOADER INSTALLED

17 Deployer Phases 17 > NOT_INSTALLED, start here > PARSE, generate metadata (from x ml, properties, etc.) > POST_PARSE, transform metadata > PRE_DESCRIBE, apply default dependencies > DESCRIBE, establish final dependencies > CLASSLOADER, create the classloaders > POST_CLASSLOADER, classloader dependent work (AOP, annotations) > PRE_REAL, last chance to transform metadata > REAL, create the runtime components > INSTALLED, fully initialized runtime component

18 Deployers 18 > New configuration dir deployers New!

19 Example: JSR (Web Beans) deployers 19 [snip] <!- - Responsible for discovering Web Bean files - - > < bean name= "WebBeansFilesDeployer" class= "org.jboss.webbeans.integration.deployer.metadata.webbeansfilesdeployer"/ > <!- - Responsible for discovering Web Bean classes - - > < bean name= "WebBeansDiscoveryDeployer" class= "org.jboss.webbeans.integration.deployer.env.webbeandiscoverydeployer"/ > <!- - Responsible for dynamic ejb dependency creation - - > < bean name= "DynamicDependencyCreator" class= "org.jboss.webbeans.integration.deployer.env.dynamicdependencycreator"/ > <!- - Responsible for booting Web Beans - - > < bean name= "WebBeansBootstrapDeployer" class= "org.jboss.webbeans.integration.deployer.env.webbeansbootstrapdeployer"/ > <!- - Responsible for pushing the Web Beans RI onto the application classpath - - > < bean name= "WebBeansWebUrlIntegrationDeployer" class= "org.jboss.webbeans.integration.deployer.cl.webbeansweburlintegrationdeployer"/ > [snip]

20 TorqueBox.org (Beta) JBoss Rails Deployer(s) 20 > Deploy Enterprise Ruby- on- Rails applications on JBoss > Include support for Job Scheduling, Task Queues, SOAP handling, SIP(Telecom) > Get clustering functionality and cloud deployment right out- of- the- box

21 Directory Layout 21 > New top level dir - common Libraries shared between configs for now New! > New configurations standard, the EE5 TCK certified config web, basis for EE6 web profile New!

22 Boot Sequence 22 > bin/ run.sh [ c < config> ] start Microcontainer using predefined < config> > Load server/ xxx/ conf/ bootstrap.xml <?xml version= "1.0" encoding= "UTF- 8"?> < bootstrap x mlns= "urn:jboss:bootstrap:1.0"> < url> bootstrap/ logging.x ml< / url> < url> bootstrap/ vfs.x ml< / url> < url> bootstrap/ classloader.x ml< / url> < url> bootstrap/ aop.xml< / url> < url> bootstrap/ jmx.xml< / url> < url> bootstrap/ deployers.x ml< / url> < url> bootstrap/ profile.x ml< / url> < / bootstrap>
